What's this tool called?

[part-timer]

I'm based in the USA, but I found this picture on a now-closed UK-based eBay auction.
I'd like to have one - does anyone here happen to know what they're called? And if they're commercially available?
If I can't find one to buy, I might have to make one - or have it made for me.
Thanks in advance.

Adjustable tap and reamer wrench?

Agree with EW. Looks like a tap handle, and a nice one, at that.

It is indeed a tap wrench. USA folk possibly;y call them something else. QV Amazon and RS Components.

Thank you all, gentlemen. After a bit of poking around the internet, the important search term to include is "offset" tap wrench or handle. I see that other makers besides Irwin make them, among them being Hanson and Vermont American.
I have a very small tap (a #5-40 bottoming tap) that I need to hold. The square portion at the back end measures only 0.110" across the flats. If that Irwin handle will hold my tap, then I've found a candidate! If not, a similar tool appears simple to make.
Thanks again!

I like it when a craftsman is proud enough of his work to sign and date it. That one is really special.

I have to agree! It appears to be quite well made. And in good condition, as well. I'd be proud to own it, as I imagine most of us here would be.
